Atlantic Bonito
Atlantic bonito show up along Brazil's southeastern and southern coast as part of their western South Atlantic range, appearing south of the Amazon mouth down toward northern Argentina.
They run in schools near the surface, chasing baitfish close to shore and offshore alike. Brazilian sport anglers target them from boats and the beach, and the fish pulls hard on light tackle — a genuine pelagic fight in accessible water.
Scientific Name: Sarda sarda
Also known as bonito, bonito-do-atlântico
- Torpedo-shaped, fully scaled body with a silvery-chrome finish and a greenish or bluish sheen along the back.
- Distinctive dark diagonal stripes running across the back — the key mark that separates Atlantic bonito from false albacore and other lookalikes.
- Large mouth with conical teeth; forked tail built for sustained speed in open water.
- Common size around 50 cm and 2–4 kg; maximum recorded around 91 cm and 11 kg.
What to know
Habitat Distribution
- Native to the Atlantic Ocean; in the western Atlantic its South American range runs from Colombia and Venezuela south of the Amazon River down to northern Argentina, including Brazil's coast.
- A pelagic, schooling species that lives near the surface — the epipelagic zone — and is regularly found close to shore as well as further offshore.
- Prefers subtropical water temperatures roughly between 12°C and 27°C, which shapes where and when it appears along Brazil's coast.
- Generally absent from most of the Caribbean Sea, so Brazil's southeastern and southern coastline sits at the heart of its South American range.
Key Locations
- The southeastern Brazilian coast — from the states of Espírito Santo south through Rio de Janeiro, São Paulo, and Santa Catarina — sits within the species's documented South American range.
- Waters south of the Amazon River mouth mark the northern boundary of their consistent presence along Brazil's Atlantic coast.
Specific Spots
- Follow the birds — diving seabirds mark active schools pushing baitfish to the surface, the most reliable sign of bonito in the area.
- Current lines, temperature breaks, and color changes offshore concentrate schools; bonito use these edges to corner prey.
- Near the beach, look for baitfish activity in the surf zone or just beyond the breakers — bonito will push sardines and anchovies right to the sand.
- Around structure such as rocky points, headlands, and nearshore reefs where baitfish stack up and bonito make repeated passes.
Atlantic Bonito FAQ
Answers from onWater's species guide.
What are the best lures and bait for Atlantic Bonito?
Metal casting spoons and chrome casting jigs in the 20–60 g range are the go-to; retrieved fast across the surface or just below it, they match the profile and speed of fleeing baitfish.
What flies work for Atlantic Bonito?
Clouser Minnows (which imitate baitfish) in white, chartreuse, or blue-and-white on size 1/0 to 2/0 hooks are a reliable starting point, the weighted eyes get the fly moving with a jigging action bonito find hard to ignore.
When is the best time to fish for Atlantic Bonito?
Bonito follow warmer water; along Brazil's southeastern coast they tend to be most accessible during the warmer months (roughly October through March) when sea surface temperatures peak.
How do you catch Atlantic Bonito?
Brazilian anglers most commonly target bonito from boats, either trolling lures or casting to visible surface schools. Shore fishing from rocky points and beaches is also productive when schools push baitfish close to the coast.
What do Atlantic Bonito eat?
Primarily small schooling fish, sardines, anchovies, and similar baitfish, which is why fast-retrieved metal spoons, casting jigs, and slender hard-bodied lures that mimic a fleeing baitfish draw strikes. Also eat squid and small crustaceans when available; soft-plastic shads and squid-pattern lures cover these bases.
